Dec 21, 2012 is simply the end of the Mayan calendar. People are taking out of context. It simply means that it's the end of the "cycle" or whatever. The mayans categorized their years much like we do (decades, centuries, etc). I don't recall what they called it but Dec 21, 2012 is the end of their cycle.. and on Dec 22, 2012, the new cycle beings... just like our centuries do.
